Controller Input Test
NOTE: 8e careful not to damage the controller and the
instrument panal.
1. Remove the instrument panel lrom the dsshboard
{see page 23-1181.
2. Remove the dash lights b.ightness controller {rom
the dashboard. then disconnect the 3-P connector.
Inspect the connector and socket terminals to be
sure they are all making good contact.
a lf the terminals are bent. loose o. corroded, repsir
them as necessary, and recheck the system.
a It the terminals look OK, make the tollowing in-
Dut tests at the connector.- lf any test indicates a problem, find and cor-
rect the cause, then recheck the system.- lf all the input tests prove OK, the dash lights
brightness controller must be faulty; replace it.
